Best Telescope for Gadget Lovers: Celestron NexStar Evolution

Hailed “the coolest app-cessory in the galaxy” by, NexStar Evolution isn’t just the Best Telescope for Gadget Lovers, it’s a game-changer for amateur astronomy. This Schmidt-Cassegrain telescope, available in 6”, 8” and 9.25” apertures, generates its own WiFi network, so you can control it wirelessly using your smartphone or tablet. SkyPortal, Celestron’s free app for iOS and Android, provides an intuitive, user-friendly experience under the stars. In addition to wireless telescope control, it also includes a full-featured planetarium with over 120,000 celestial objects and audio descriptions for hundreds of the most popular planets, galaxies, and nebulae.
As if communicating wirelessly with your phone wasn’t cool enough, NexStar Evolution offers other enhancements to make your stargazing experience seamless. It’s the first telescope with a built-in lithium ion battery with enough juice to power a 10-hour stargazing marathon. There’s also a USB port so you can tap into the battery to charge up your mobile device if it’s running low. With NexStar Evolution on the scene, stargazing will never be the same.

This NexStar Evolution 925 advanced 9¼" f/10 Schmidt-Cassegrain is the first go-to telescope (along with the other new NexStar Evolution scopes) with built-in WiFi so you are not tethered to your scope by a hand control on a coiled cord. You can slew to all of the best celestial objects with a simple tap on your smart phone or tablet.

Simply connect your smart phone or tablet to your NexStar Evolution 925’s built-in wireless network, and you can explore the universe with Celestron's mobile app for iOS and Android. The app has a database of over 120,000 celestial objects for you to explore, including a specially selected list of 220 of the best deep sky and solar system objects that you will come back to enjoy again and again.

You can use the app’s planetarium interface to view the night sky in real time or to display a list of the best celestial objects that are visible to you based on your time and location. You can then command your Evolution 925 to automatically slew to the object of your choice at speeds of up to four degrees per second, center it precisely in the eyepiece field, and then track it flawlessly while you observe and enjoy at your leisure. In addition, Celestron’s proprietary SkyAlign alignment procedure is built right into the Celestron mobile app, so you can have your scope set up and ready to observe within minutes. (If you don’t have a wireless device, or your smart phone or tablet runs out of juice in the field, a conventional hand control is included so you can still enjoy your scope.)

Celestron engineers designed the NexStar Evolution 925 based on years of customer feedback. It has an upgraded single fork arm design with many thoughtful features that combine to provide you with the best possible experience out under the stars. For example, forget about buying boxes of AA batteries to power the scope, or a bulky external battery pack. For the first time ever on a consumer telescope, the NexStar Evolution 925 includes its own built-in rechargeable lithium-ion battery. You can enjoy stargazing for up to 10 hours on a single charge, then recharge it at home using the supplied AC adapter. You can even use your NexStar Evolution 925’s built-in USB charge port to top off the other devices in your life that need to stay powered on during an observing session.

Large, ergonomic handles make setting up your NexStar Evolution 925 quick and painless. With a total weight of only 46.6 lbs, the Evolution 925 is easy to transport, whether it's out to the backyard for a quick half hour of observing or away on an all-night observing session at a distant dark sky site. The heavy duty adjustable height stainless steel tripod features lines etched on the legs to help you achieve a level, uniform height for your telescope without guesswork.

Manual clutches in both altitude and azimuth give you the flexibility to manually point the telescope when it is powered off. You get two quality Plössl eyepieces to give you observing options right out of the box. If you expand your eyepiece collection, you can store up to seven eyepieces in the two accessory trays, one on the tripod and one on the telescope drive base. An adjustable brightness red LED in the fork arm casts a soft red glow onto the accessory tray in the base to make it easier to select a different eyepiece while observing.

If you’re interested in astroimaging, the 9¼” NexStar Evolution 925 is an affordable way to get started. It’s the only fork-mounted telescope in its price range that offers precision worm gears, along with improved motors, for precise speed control and low periodic error. With the NexStar Evolution 925’s good tracking accuracy, you can capture images of deep-sky objects like the Orion Nebula by simply attaching your DSLR camera. As you progress in the hobby of astroimaging, you can add an optional Celestron HD Pro wedge for longer exposures to bring out faint and hidden details in your astrophotos.

Celestron's time-tested 9¼" Schmidt-Cassegrain optics and industry-standard StarBright XLT optical coatings give you the bright, sharp views for which Celestron is famous. They make the Evolution 259 a great choice for visual observers and budding astroimagers alike.

The NexStar Evolution 925 includes built-in WiFi for cordless operation, a StarPointer red dot finderscope, two 1.25” Plössl eyepieces (59x and 180x), a 1.25” prism star diagonal, an AC adapter for powering the scope and recharging the built-in battery, a computer hand control, and a heavy duty stainless steel adjustable height tripod with accessory tray

WiFi Tips for NexStar Evolution

Please note the following for the most reliable WiFi connection to the telescope:

Areas with high WiFi traffic, such as large star parties or crowded public spaces, can potentially pose difficulties connecting to the telescope. Additionally, multiple smart devices and multiple WiFi telescopes in the same area can generate conflicting traffic. Follow these tips to maintain the most robust connection to your telescope.


  1. If you experience lag or connection problems in areas with high WiFi traffic - To minimize possible connection problems in high traffic areas, select a viewing site with minimal WiFi traffic. Numerous nearby devices with WiFi enabled can contribute to unwanted WiFi traffic. Disabling WiFi in nearby devices can improve connectivity to your telescope. Alternatively, high traffic areas may require the use of the included NexStar+ hand control instead of the SkyPortal app over WiFi. 
  2. If you experience conflicts when using multiple devices to control a telescope - If you have multiple smart devices, and have connected to the same WiFi telescope previously with them, then be careful of both devices unintentionally communicating to the telescope at the same time. For example, if you have previously used your smartphone to control the telescope and later use a tablet to control the same telescope, the smartphone may interfere with the telescope connection. We recommend “forgetting” the telescope WiFi network with any smart devices not currently in use.
  3. If you experience conflicts when multiple WiFi telescopes are in the same area - If you are using multiple WiFi telescopes and have connected to them with your smart device previously, we recommend “forgetting” the other telescopes/devices not currently in use. This way, you won’t accidentally connect to the other telescopes/devices. This is especially useful at a star party where more than one WiFi telescope may be in range.
